DAVID A. HOOVER, OF PORTLAND, INDIANA.

OIL-BURNER.

Specification of Letters Patent.

Patented Sept. 29, 1914.

Application filed January 10, 1914. Serial No. 811,287.

To all whom it may conoci-n citizen of the United States, residing in the city of Portland, in the county of Jay and State of Indiana, have invented certain new and useful improvements in Oil-Burners, of which the following is a full, clear, and comprehensive specification and exposition, being such as will enable others to make and use the saine with exactitude.

This invention relates to fuel-oil burners, the same being particularly adapted for cooking-stoves or ranges.

The object of my present invention, broadly speaking, is to provide an oilburner which will be strong and durable in construction, easily operated and controlled, capable of developing a maximum of eflicieney in practice, adapted to consume a minimum of fuel in operation, and which can be manufactured and sold at a comparatively low price.

The more distinctive objects of this invention are: the provision of an oil-burner having a plurality of combustion points with means for the delivery of the gaseous fuel thereto whereby the various flames will be equal in capacity and intensity with relation to each other; to provide a generator for developing gas from the liquid fuel; to provide a controller or damper for regulating the delivery of air to the combustion points; and to provide a substantial base by which the burner will be retained in proper l position.

Other objects and particular advantages of my invention will be brought out in the course of the following description.

The preferred manner for the construction of my invention is shown in the accompanying drawings, in which- Figure 1 is a side elevation of the invention complete. Fig. 2 is a central vertical section taken through the construction shown in Fig. 1. Fig. 3 is a top plan of the body portion, partly in section, taken on the line 3 3 of Fig. 1. Fig. 4l is an inside plan view of a portion of the bottom of the base, as taken from the interior of the air-chanr ber. Fig. is a cross section, as taken on the line 55 of Fig. 1, and Fig. 6 is a perspective detail view of one of the deflectors, and a portion of the generator pipe.

Similar indices denote like parts throughout the several views. y

In order that the construction, the operation, and the advantages of my invention Be it known that I, DAviD A. Hoovnn, a

may be better understood and appreciated l will now take up a detailed description thereof in which l will set forth the invention as comprehensively as I may.

Referring now to the drawings in detail, letter A designates the body-plate, the same being oblong in shape, and having a flange extending up entirely therearound from its edge, and a like flange a extending down entirely therearound from its edge. Extending across the upper face of the plate A are the flanges a and af which correspond with the flange a.

Adjoining the inner edges of the flanges or ribs o and a" are the respective air supply cones B and B which slope upward and with comparatively large apertures b and b formed through their center, as shown in Fig. 3. Extending longitudinally of the plate A. and dividing said apertures b and b each into two parts are the respective webs b and 5', which are located at the bases of the burners.

Letter (d denotes the air-chamber, which is in the nature of box-like structure having side and end Walls and a bottom, and being of such dimensions that the upper edge will fit around in the flange o as shown, with the plate A forming the top of the air-chamber. Formed through the center of the bottom of the air-chamber is an aperture x for the admission of air into the air-chamber.

Letter l) denotes a damper, which is merely a flat plate adapted to slide on the bottom of the chamber C, and when in one position it will close the aperture Secured to one edge of the damper D is the rod d which extends out through an aperture in the wall of the air-chamber and provides means for operating the damper from outside the air-chamber.

Extending upward from the center of the outer end of the plate A is a hollow or channeled standard E. And extending up from near the inner end of the plate AV is the supporting standard F, in the fork of which may rest the inner end portion of the generator pipe 1. Threaded onto the outer end of the generator pipe is the angular fitting 2. which extends down through the channel of the standard E and then outward to one side as indicated. v

Numeral 3 denotes a conveyer pipe which is connected to the lower portion of Ithe fitting 2 from' which it proiects outward to near the edge of the plate A and then eX- tends along the edge of the plate A to near the center thereof, and then turns inward or centerward. Secured on the inner end of the pipe 3 is the T-tting 4 which is located at the center of the plate A.

Extending from the T-iitting 4, parallel and in alinenient with each other, are the two burner-pipes 5 and 5, the same being equal with each other in length, and they are located directly below and parallel with the pipe l. Closing the ends of the pipes 5 and 5 are the respective caps 6 and 6, said caps being' located near the respective standards F and E. It will be observed that the pipes 5 and 5 rest on the respective webs 7) and 5', there being notches formed in the air supply cones B and B in which said pipes rest as is indicated. .'"in aperture or vent 2 is formed in each of the pipes 5 and 5. the same being directed directly upward, as shown, and they are located concentric with the respective apertures b and b.

tlidably mounted on the pipe l are the two round detlectors 7 and 7, each of said deflectors has a recessed lower face which is formed by a peripheral flange or lip y, through which lip are formed a plurality of notches u. Said deflectors are adapted to be located above and concentric with their respective apertures 2f, as shown in Figs. l and Attached to the inner end of the pipe 1 is the elbow 8.

Numeral 9 denotes the controller valve. Connecting the valve 9 with the elbow 8 is the pipe l0. Numeral 1,1 denotes a portion of the oil supply tank, which is connected to the valve 9 by the pipe 12, as is indicated in Fig. 1.

Modus operandi: Suppose now that the burner be located inside the fire-box of a stove or the like, with the bottom of the chamber C resting on the stove-grate in such manner as to allow air to pass up through the stove-grate and through the aperture when it is open. The tank 11 should be placed at a distance from the burner and then connected to the burner, substantially as shown.

Now if the valve 9- be closed and the tank 11 contains a supply of oil, the operation l plate having air apertures therethrough, an

well be substantially as follows: The valve 9 may be slightly opened, allowing a small amount of oil to escape through the apertures e and adhere to the burner pipes 5 and 5. The valve should then be closed and the escaped oil may then be lighted and the heat rising` therefrom will heat the pipe 1, after which the valve may again be opened, thereby causing the pressure to force the gas out through apertures s. The heat from the escaping gas forming a flame will So heet the pipe l that the oil as it enters therein will be converted into gas, whereby as soon as the burner s Proprly heatedvthe discharge from the vents e will be in gaseous form, which gas will continue to be generated as long as the burner is kept lighted and in operation. The proper combustion may be obtained by regulating the supply of air to the burners, that is by manipulating the damper D as required.

It should be observed that the delivery of the fuel to the burners is such that the llames be of equal intensity; also the entrance of the fuel to the burner pipes is located at a maximum distance from the flames, thereby preventing the joints from becoming loose on account of the heat, which has heretofore been a source of much trouble in burners of this general character.

The construction of the lower faces of the deiiectors is such as to cause the flame to concentrate therein and then be deflected out through the notches la in tine streams, which will cover a large amount of surface to be heated thereabove.

itttention is called to the fact that the burner pipes and the generator pipe, which are connected together, are retained securely in operative position by the means set forth, yet they may be easily lifted from the body of the burner after being disconnected from the tank.

The detlectors may be rotated on the gcnerator pipe` in order to place their under faces at an angle, in place of parallel with, the surface of the plate A, in order to deiect the heat more forward or rearward in the stove in which the burner is employed.

I desire lt to be understood that this invention is not to be limited to two iiames, as herein provided, it being understood that a greater number of Harnes may be provided for if desired.

I desire that it be understood that various changes may be made in the several details of construction, from that herein set forth, without departing from the spirit of my invention and without sacricing any of the 110 advantages thereof.

Having now fully shown and described my invention, what I claim and desire to secure by Letters Patent of the United States, is I l. An oil-burner consisting` of a bodyair chamber located below the said plate, means for controlling the admission of air into the said air chamber, a generator-pipe extending across longitudinally of and above the said plate, means for removably securing the generator pipe above the plate,
